+* Colors now work on the Windows commandline (thanks to @MinchinWeb). Requires
+  colorama to be installed.
+* Do not print spurious color codes when colors are disabled in the
+  configuration (thanks to @MinchinWeb).
+* In prompt mode, restore old auto-completion behavior: press Tab for
+  completion (instead of complete while typing).
